It provides a comfortable user interface to perform most CD/DVD burning tasks, such as creating an audio CD from a set of audio files or copying a CD.

BlueProximity helps add a little more security to the desktop. It does so by detecting a certain Bluetooth device, most likely a mobile phone, and keeping track of its distance. If it is moved away from the computer and the distance is above a certain level (no measurement in meters is possible) for a given time, it automatically locks the desktop (or starts any other shell command wanted). Once away, the computer awaits its master's return: if the device is nearer than a given level for a set time, the computer unlocks without any interaction (or starts any other shell command wanted).
KDelicious adds several options to the Konqueror (right-click) Action menu, allowing you to use the del.icio.us Web site in various ways.

It integrates seamlessly with KDE and KWallet, which means proxy connections and secure password storage are supported.
